1 Claim. (Cl. 143-158) This invention relates to meat cutting apparatus and is particularlydirected to improvements in band saws for cutting meat and bone.

Chops and steaks and other cuts of meat are often individually wrapped in transparent packages and marketed 1 in serve-yourself type retail stores. Packaged meat cuts of this, type as well as those displayed without dividual cuts of meat to remove bone-dust. Another object is to provide an improved form of band saw blade for cutting meat and bone which operates to collect the bone-dust as it is being formed and to provide novel Other and more detailed objects and advantages will appear hereinafter.

In the drawings:

Figure-l is a side elevation in diagrammatic form showing a meat cutting band saw device embodying my invention.

Figure 2 is a side elevation on an enlarged scale'showing details of the band saw blade. I

Figure 3 is a sectional elevation taken substantially on the lines 3-3 as shownin Figure 2. I

Referring to the drawings, a frame generally designated it? supports a pair of vertically spaced pulley wheels 11 andlZ. An endless band saw blade 13 is trained over United rates Patent 2,978,001 Patented Apr. 4, 1961 Means are provided for removing the bone-dust from i the blade 13 after the blade has travelled through the aperture 15 and prior to its initial contact with the lower pulley wheel 12. As shown in the drawings this means includes a pair of power driven rotary brushes 27 and 28 adapted to contact the side faces 19 and 20 of the -blade'13 respectively. The brushes 27 and 28 are individually driven from electric motors 29 and they are adjustably mounted on the frame 10 in a manner so that they may be canted or tilted as desired. The brushes 27' and 28 serve to remove the bone-dust from the projections and pockets on the side faces of the band saw blade 13, and the bone-dust as thus removed may be allowed to collect in a sediment chamber or disposed of in any suitable manner. Since the dust does not remain on the blade. 13 it is not carried around the pulleys '11 and 12. The coating of bone-dust on the individual cuts of meat is substantially eliminated.

the downward-moving flight of the band saw blade, one I, V edge of the band saw blade having teeth thereon, the side faces of the band saw blade having longitudinally spaced ridge elements extending substantially at right angles to the directionof movement of the blade, each of said ridge elements terminating short of the side edges of the blade, and being adapted to collect bone-dust produced by the saw teeth, and a pair of power driven rotary brushes positioned on the frame below said platform,

'7 each of said brushes contacting one side of said blade,

the pulley wheels 11 and 12, and the downward moving j wheels.

laterally directed projections 01' ridges 21 and 22. I These ridges 21 and z z-projectalternately from opposite'fac es flight thereof 14 passes througha clearance aperture 35 provided in the stationary platform 16. This plat- I form "16 is supported on the frame 10in a position be-.. I tween the pulley wheels 11 and 12 Conventionalmeans :5 (notshowri) are provided for driving one of the pulley r of the blade 13; the ridges 21 project from the face 19 a I fand the ridges 22 project from the face 20. 'A pocket 23.

is formed adjacent "each of the projecting ridges. I have the parts of each rotary brush contacting the side faces of the blade moving substantially parallel to said ridges.
